Key notes
- Many users reported that the CMD Tab autocomplete was not working after a Windows update.
- The problem is common and arises due to changes automatically made after an update is installed.
- To fix things, modify the Registry or run two quick commands, as described below.
The Command Prompt has a handy little autocomplete feature allowing users to change directory paths using the Tab key. However, several users have reported Tab autocomplete is not working in CMD on Windows.
This issue can occur if the Completion Function is disabled in the registry. This can happen after installing new Windows updates, which may have disabled the feature. Keep reading to find out how to enable Tab autocomplete in Command Prompt and Terminal.
How do I turn on Tab autocomplete in CMD?
1. Enable autocomplete through Registry Editor
- Press Windows + R to open Run, type regedit and click OK.
- In the Registry Editor, navigate to the following locations and locate the CompletionChar entry:
HKEY_CURRENT_USER\Software\Microsoft\Command ProcessorComputer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor
- Depending on the Windows release, you will find the Command Processor in one of the above directories.
- From the right pane, double-click on the CompletionChar DWORD.
- In the Value data field, enter 9 and click OK.
- Next, double-click on PathCompletionChar and set the Value data to 9 as well.
- Restart the computer for the changes to come into effect.
When CMD Tab autocomplete is not working, modifying the Registry, i.e., the CompletionChar and PathCompletionChar DWORDs, should get things up and running.
2. Enable tab autocomplete using Command Prompt
- Press the Windows key, type cmd, and click on Run as administrator.
- In the Command Prompt, enter the following commands individually and hit Enter after each:
reg add "hkcusoftwaremicrosoftcommand processor" /v CompletionChar /d 9 /t REG_DWORD /freg add "hkcusoftwaremicrosoftcommand processor" /v PathCompletionChar /d 9 /t REG_DWORD /f
- The above commands will add the required registry values to the registry.
- Restart the computer for the changes to apply.
